There are some villains that Jimmy had defeated that were not members. Their meeting place was the Junkman's ship. They appeared in the episode of the same name but, by then end of the episode, Zix, Travoltron, and Tee had quit the alliance, and the rest were trapped in the past. Meldar Prime, Dr. Sydney Moist and Evil Jimmy are not in the League of Villians.
